axe-selenium-python 0.0.441

Python library to integrate axe and selenium for web accessibility testing.

axe-selenium-python integrates aXe and selenium to enable automated web accessibility testing.

Requirements

You will need the following prerequisites in order to use axe-selenium-python:

• Python 2.7 or 3.6

• pytest-selenium >= 3.0.0

• tox

• geckodriver downloaded and added to your PATH

Installation

To install axe-selenium-python:

$ pip install axe-selenium-python

To install pytest-axe:

$ pip install pytest-axe

Usage

test_accessibility.py

import pytest

 @pytest.mark.nondestructive
 def test_header_accessibility(selenium, base_url, axe):
     selenium.get(base_url)
     violations = axe.run('header', None, 'critical')
     assert len(violations), axe.report(violations)

The above example runs aXe against only the content within the <header> tag, and filters for violations labeled critical.

The method axe.run() accepts three parameters: context, options, and impact. For more information on context and options, view the aXe documentation here.

The third parameter, impact, allows you to filter violations by their impact level. The options are critical, severe, moderate, and minor, with the default value set to None.

This will filter violations for the impact level specified, and all violations with a higher impact level.

Command Line Argument

$ pytest --base-url http://www.mozilla.com --driver Firefox test_accessibility.py
